How to create a material of horizontal black and white lines
Just a 'Texture Coordinate' node and plug it into a 'Mapping' node. Now you are able to split the output vectors with a 'Separate XYZ' node. If you plug b.e. the 'z'-Value of the 'Separate XYZ' node in the vector of a 'Checker Texture' node, you will get strips along the z-axis, same for the x, y.. with some vector math you can easily manipulate the result
